Disney’s “Monsters University” is the weekend box-office winner, according to studio estimates released Sunday. The animated family film, which reunites stars Billy Crystal and John Goodman and their characters from the 2001 hit “Monsters, Inc.,” debuted in first place with $82 million, beating out swarming zombies in “World War Z” and Superman himself in “Man of Steel.” “The diversity of this weekend is part of what makes this business so great,” said Dave Hollis, Disney’s head of distribution. “It’s a really extraordinary weekend for the industry.”
